BLOWPIPE ATTACHMENT FOR GRAIN-SEPARATORS. y

Application filed January 25, 1919. Serial No. 273,086.

To all whom t may concern.' i

Be it known that I, JOHN F. WEGERER, a citizen of United States, residing at Marion, in the county of Marion, State of Kansas, have invented certain new and useful Improvements in Blowerpipe.Attachments for Grain-Separators; and I do'hereby declare the following to'be` a full, clearand exact descriptibnv of the invention, such as will en.- able others skilled in the art to whichit appertains to make and use the same.

This inventionl has reference to the class of threshing. or separating machines, and more `particularly to `an 'improvement yin blower pipes therefor.

by the invention to provide.` 1an. improved blower pipe for threshers or other grain separating machines, or an attachment therefor particularly designed for use in the threshmg of wheat, so that the grain is carried along with the cha-ff and straw, into the 'blower pipe, will be effectively separated therefrom and automatically discharged to be caughtin ya suitable receptacle, while the chaff and straw will be blown from the pipe in. the usual manner, on to theV Stack. By. this means, a considerable saving in grain production is accomplished, as ordinarily, a large quantity of grain which is not threshed out, is carried alongiwith .the chaff andstraw, irrespective of how closely the cylinder and concave teeth may .be positioned, and it will thereforebe obvious that in view of the large number of `machines in use, an enormous saving will thereby be effected, thereby mafterially Vincreasing` the grain or wheat production. 1 v l HA still-further `object of the invention is to provide an improved :attachment for an Avery or other ,l improved type of blower, in `which thereis disposedl at the elbow of the blower or point vof bend thereof remote from y i @the dischargeand throughwhich the grain,

'straw and chaffis discharged, fanovel arrangement of parts whereby the grain carried along with the straw y and chad, will be `caused to be deflected into an enlargement of the,` blower pipe whilev permitting the straw and chaff' to be `carried in the usual manner for discharge from the blower pipe,

`such attachment embodying a novel lform of Iscreen device permitting the passage of a maximum quantity of the grain and but a minimum quantity ofthe 'straw and chaff, into said enlargement, after` which, ythrough Patented July 8, 1919.

the medium of a novel arrangement of baffle walls, the grain is caught and discharged from either side of the blower pipe, in a condition free from foreign matter, chaff, straw or dirt, thereby greatly increasing the power of the machine to produce usable grain. Vhile I have particularly specified the use of the'device` in connection with the threshing of wheat, I desire to have it understood that the improvement can be employed with various grains, as occasion shall arise.

Vith the above objects and others in view, as will appear as the specification proceeds, the invention comprises certain novel combinations and arrangements of parts as will be hereinafter more particularly pointed out in the accompanyin@ description and claims.

Reference is hac to the `accompanying drawings forming a part of this application wherein like reference characters designate similar parts throughout the several views, and wherein;

,threshing machine proper, to a point horizontally for discharging the chaff and straw,

from whichthe grain has been separated, to

yproduce a stack or as it may be stated, blowing the straw and chafl", to .stack the same. Moreover, it is impossible to separate all of the grain from the straw and chaff', that y is, not all -of the heads, no matter how closely thecylinder and concave teeth may be positioned or engaged, with respect to each other, or how much speed is imparted to the .cylinder in the threshing or separating action and therefore, with the ordinary blower,

there is a considerable quantity of grain car- Y rlcd along with the chaff and straw, and` which is therefore wasted.

In order to obviate-thisA waste, 'provide the improved blower or attachment for the ordinary pipe which consists in providing the top or thepipe, adjacent'to-the elbowan opening 11, andlat a point'iin the' ftop' tot the pipe `remote from the' elbow-and thefopening ll, an opening 12.` Said 'partition maybe otherwise suitably Jformed. "It willthusbe vseen that thelenlargement@through the inedium of the inclined 'end walls 8 and v9',fw`ill provide for ythe eiticientF-defllectior and I"discharge of air through the pipefas' will 'be later` described and in a maniiertoiobviate thepossible obstructionvofltheblower pipe in the operation of separatingthe"` straw and chaff from the grain andstacking the same, as it is `thought will be understood by any one acquainted with f the Vart.'

Within the housing of the raised portion or enlargement 7 and-extending longitudinally of Vthe o'pening1l,'isv a "wire 'screen 13, comprising aseries ot"independent-wires placed in parallel relation las closely'- asopos- Y '5 sible, consis'tent with the properpassage of the grain or heads ofthe graintherethrough, after Abeing discharged -or blown ifrom the threshing mechanism, while also consistent `V with the passage of a-minimum'-qiiantityfif not excluding all"l of the straw and 'Chatfor other l'foreign 'matten 1\"rbm""pass\i ng therey Inthis connection, it shouldfbe'notedfthat thefscreen is/plac'edfat slight incline,'fso

as :to oifertheleast possible obstruct-ion'ffto while freely I permitting lthe passage Eof `the grain therethrough, under the suction vaction created in theblower pipe. This screen 5 also entirely spans the openingll, and above" the adjacentend of the partition 10 provided by `the intermediate 'portion of *the upper' part ofthe pipe producedbythe openings llfand 12 heretofore described, whilef'in order to hold fthe suction in the upper partv offthe housing,` and to insure proper suction inthe lower part for properly carrying or conveying the straw yand chaff through the blower pipeand discharging the same, the opposite `or-remote end ofsa-idpartition is bent downwardly as shown at 14 in the form of a deiector. This is due to the fact thatthe outlet below the partition 10 is restricted, 'there :by-creating,a'suction in front of the lower chamber or' the enlargement or pipe at this point. Y

Arranged against the `top portion' of the Wall 'of the enlargement'or housing 7, is a substantially angular baiiiewall or plate 15,- of concavo-convex cross section and or curved contour so as to lit the :inner surface ofthe topportion of lthe housing.'k Positoned at a spaced distancebelow and 'in advance offthe baflierwall-or derlector l5, and upon the rpartition or :top fportion :10 of lthe pipe proper,iis lan oppositely disposed baiiie plate orldefiector 16 also ypreferably of concavo-convex cross' section in itspreferred construction `and spaced from :the deflector l5, as previously stated. Thisdeflectorl is made inthe iform of atrongh, Asot-hat it will retainthe grainzthereonpin'-a manner tobe hereinafter lmore particularly describechxin connection `with theroperation of the device, andhasy at its opposite endsj'leading:through diametrieally:opposite points ot the sides or the *blower -pipeand downwardly along the same, discharge pipes 1-7l through which the grain' is discharged'and maybe caught -in a suitable'recept-a'cle -or ,fbucket provided under it.

In lthe operation ofthe device, it is tof-be understood'that they shocks of grain are to'be fed-into the thresher or separating'machine inthe usual imanner and will be acted upon by theficylinder.mechanism 'to knock or separate the heads ofi the 'grains from 4the' straw andchaiil' or other foreigny matt-er.v @rdinarily, Lthe -grains are ldeliveredy separately r'rointhe straw and chaii,but owing to Ilthe large quantity of `'grain being carried along with fthe" lstraw and chatlfy to be stacked', in passing through the blower, the grainfis 'eaused'to u strike the inclined lscreen 13 and g'ra'i'ns' Vwill then st'rikethe derle'ctor 15 yand -becausedtofbefdischargedf or deflected downwardlyon `tothe baife wallsl or trough produced thereby, the graiir beingdis'charged through the p'ipesfras Athe operation is 'carried on.`v 4Tini-this 'connecti'on; it isl to "be understood "that a certain amount of airpasses Athrough *the screen vand upper "chamber *through '1 the openings 'Ilf'and 12, and out 'throughthe blower pipe-to create suction in connection'w'ith theairpassing through the lower chamber-or pi'pcproper and under the detlectorJ-orb'aiiie "wall vvpart 14, the i"major portion "ifnot allofthe straw, chaff and foreign matter being blown or discharged through the pipe without entering the upperr chamber to choke or clog up the same.

In this manner, a considerable quantity of grain which would otherwise be thrown on to the stack and wasted, is saved the importance of which is very obvious. It is also to be understood that the housing 7 may be securedin any suitable manner to y,the blower pipe, so as to be removable toa v gether with the wire screen 18, so that the openings 11 and l2- can be closed when threshing Kaiir ycorn or fodder, or the like. Havingthus described my invention, what i' I claim and desireto secure by Letters Pati the end remote from the discharge end of the blower pipe, and bafile plates in the upper chamber having a discharge spout.

l 2. An improved blower pipe for grain a separating or harvesting machines, comprisinga pipe proper having spaced openings therein, a raised housing on the pipe, the

pipe between said opening forming an intermediate partition, yproviding upper and lower chambers, a` screen at the end remote from the discharge end of the blower pipe, said partition having its remote end bent downwardly a baiiie wall in the upper portion of the top chamber, a baiiie wall secured tosaid partition at a point in advance of the iirst named baiiie wall and spaced therefrom and a discharge spout leading Jfrom `the second named baiiie wall for the dischL rgeof the grain caught thereby. Y 3. The combination with a blower pipe of the class described having an elbow; of a housing positioned above the same, said pipe having spaced openings therein in its top portion, a screen comprising longitudinally disposed spaced wires adjacent to the elbow of the pipe and covering the opening thereat, to permit grain carried along with the chaff and straw at the top of the latter, to pass there through but to deflect the chaff and straw through the pipe proper for stacking, a concavo-convex baille wall secured inside of the top wall of the housing at the end thereof remote from the screen, a trough mounted upon the portion of the top wall of the pipe between the openings upon which the grains deflected by said baie wall are deposited, said trough sloping to the side and discharge means for said blower.

4. The combination with an angular blower pipe of the class described; of a housing positioned above the same, opposed baffle walls in the housing, said pipe having spaced openings therein in its top portion, a screen comprising longitudinally disposed spaced wires adjacent to the point of bend of the pipe, the opposed ends of the housing sloping in opposite directions to provide channels through which the air will pass with the grain for throwing the same forcedly against the baffle walls, one of said baiile walls producing a trough, said trough being of concavo-convex cross section and spaced apart with the trough forming wall located in advance of the other and the end of the top portion at the remote opening being bent downwardly, as and for the purposes specied.

In testimony whereof, I aiiiX my signature, in the presence of two witnesses.
